Frequently Asked Questions
How accurate are cannabis potency calculators?
Cannabis calculators provide estimates. Final potency can vary based on decarb, infusion efficiency, straining loss, ingredient measurements, and how evenly the cannabinoids are mixed.
How is THC potency calculated?
THC potency is usually estimated using the weight of cannabis, the THC percentage, and an estimated efficiency percentage for decarb and infusion.
What infusion efficiency should I use?
Many homemade infusions use an estimate around 70% to 85%, depending on the method, temperature, time, and how thoroughly the oil is strained.
Can I use these calculators for CBD products?
Yes, the same basic math can be used for CBD if you enter the CBD percentage or known CBD milligrams instead of THC.
